Patrol Cars Prior to 1928, inspectors only used automobiles once they had seized a vehicle used to transport illegal whiskey and it had been released to the Division for enforcement purposes by the courts. Fords became the first issued patrol vehicles in 1928. In 1932 white Chevrolet roadsters and white motorcycles were purchased and became known as the "Great White Fleet". Fords and Chevys were the main staple of the patrol force in the 1930s and early 1940s. In 1945 post-war acquisitions of police vehicles were rare and troopers made arrangements to purchase vehicles wherever they could. Buicks and Pontiacs supplemented the fleet until auto manufacturers resumed normal production. In 1948 the Department adopted the distinctive blue and gray paint scheme for all vehicles. Later in 1952 reflective markings were adopted and used for all marked vehicles. Those same markings are still in use today. During the 1940s, 50's, 60's, 70's, and 80's the Department purchased Fords,
